IMPROVEMENT IN MOUTH-PIECES AND LIDS FOR GAS-RETORTS.

speeincation forming part of Letters Patent No. lease/4i, dated July 1o,1877; appiieation sied June 5, 1877. 1

To all whom it may concern:

Be it known that I, TAYLOR UBIL, of the city and county ofPhiladelphia,'in the State of Pennsylvania, have invented certain newand useful Improvements in Mouth-Pieces and Lids for Gas-Retorts, ofwhich the following is a specification:

The objects of my invention are to provide suitable means for eecting anair and gas tight joint between a retort mouth-piece and its lid; and,further, to reduce the damage resultant from breakage of the lugs orsupports of the lid and fastening by an improved means of connecting thesame to the mouth-piece.

To these ends my improvements consist, first, in the combination of aretort mouth-piece, having a groove orrecess extending around its outerface, with a lid having a groove or recess of symmetrical outline tothat of the mouth-piece, and containing a yielding or elastic packing,which projects above its face, and

, tits into the groove of the mouth-piece, being compressed therein bythe screw and cotterbar or other fastening, by which the lid is pressedup toits position when closing the mouth-piece.

My improvements consist, secondly, in the combination of a retortmouth-piece, having a recessed side flange, with a removable hingepiecefitting into the recess of said ange, and secured thereto so as to bereadily renewed in the event of breakage, without affecting the positionor the other connections of the mouth-piece.

In the practice of gas-engineering, various expedients have been fromtime to time proposed and practiced for the purpose of preventing theentrance of air and escape of gas between retort mouth-pieces and theirlids. Various materials in the nature of` luting have been employed forthis purpose, and in some instances copper or-lead has been inserted ingrooves in the mouth-piece, and compressed therein `by a projecting ribor tongue on the lid. Fusible alloy has also been similarly employed.

- An objectionable feature in such application has, however, existed inthe fact that the packing is to a greater or less degree forced out ofits groove by the entering rib upon the application of pressure by thefastening device, and thereby exposed to the destructive effect of thedirect action of heat.

In the use of my improvement the projecting portion of the packingmaterial is covered and protected by a receiving-groove, into which itis compressed, and a tight joint is thereby insured without thenecessity of frequent renewals.

Retort mouthpieces are, further, ordinarily constructed with the lugs orbearing-pieces, to which the lid andfastenin g are to be hinged, castupon them, and in such case the breakage of a lug, which frequentlyoccurs in the operations of drawing or charging, entails the removal andloss of the entire mouth-piece. My improvement enables a broken lug tobe readily and speedily replaced without the removal of or detriment tothe mouth-piece Aor retort, or their connections.

In the accompanying drawings, Figure 1 is a front or face view of aretort-mouth embodying my improvements; Fig. 2, a vertical centralsection of the same; Fig. 3, a horizontal half-section at the line l lof Fig. l; Fig. 4, a vertical section through the side iange andhinge-piece; Fig. 5,`a view, in perspective, of l the hinge-piecedetached; and Fig. 6, a section `on an enlarged scale,showingwamodication in the form of one of the packing-grooves.

To carry out my invention, I form upon the front or face of the retortmouth-piece A a groove or recess, a, extending entirely around saidface, and being, preferably, of a curved or segmental cross-section, andupon the in side of the'lid A1 a groove, al, symmetrical in outline, orcorresponding with the groove a, but dovetailed or undercut on one orboth sides, the better to retainl the packing b, with which it isfilled. The packing may consist4 amants: i @rr-ron.

of pressure yby the 'cotiser-bar G and 1 screw i0',

, or by any other fastening device which may be employed, the projectingportion of the pack- A erable, is notfessential, and in Fig. 6 a kidneyform or triple-curve section of the groove is shown. Y

It will be further obvious that the relative positions of the retainingand receiving grooves might be reversed, it' desired, without departingfrom the spirit of my invention, the prominent feature of which consistsin providing a cover or'receptacle for the projecting portion 0f thepacking.

A side flange, A2, is formed uponthe mouthpiece A, within which flangeis formed a recess, az, to receive a removable hinge-piece, D, whichfits neatly therein, and is secured by a bolt or bolts, d. The base ofthe hingepiece D is of sufficient area to give firmness to the unionmade between it and the recessed flange, this feature causing this partof my inupon which the cotter-bar-Cand lid Al are pivoted.

In case of breakage of either of the projecting `lugs, the hinge-piececan be readily removed, and another substituted at-tritling cost,

without affecting the position of the mouth- .piece and stand-pipe.

I am aware that joints "have been made in gas-retort mouth-pieces by thecompression of a yieldingpaeking betweeu'a 4,recess and an entering ribor projection, asin the patents of .W. H. St. John, No. 16,075, November11, 1856,

and N. Aubin, No. 17,068, April 2,1, 1857. I do not, therefore, broadlyclaim" the -use of packing in combination with grooved surfaces inajoint.

I claim as my invention and desire to secure by Letters Patent- 1.Thec'ombination, witha gas-retort mouthpiece having la groove lor`recessaround its outer face, of a lidhaving a groove of correspondingoutline lilled with 'yielding `o'"f'e1as tic packing, which projects and'tits into the grooveof the mouth-piece when the lid zis closed thereon,substantially as seti'orth.

2. The combinationof .a retort'xnouth-pi'ece, having a recessedsid'eiangeI and a gremovable hingepiece,'with a plate 'fitting into therecess of said ilange, and fbolted thereto, sub-l stantially as setforth.
